' Application engiist s, 194 1," S erial'No.406,il40 I s Claims.(cizizgot) our invention relates a-imtraemens-far' n} planes and thelike and has for one object to proa e one jnalf or the Housing, thefhousing'j being bolted 'thereto as at IB. :Ifhe housing maybe vide ananchorage mechanism-which maybe'permanently attached to the plane'andibe always available for service. l

Another object of the invention is tdprovide such a mechanism as willi'nterfere'to a minimum extent 'with the-progress of th plane through Ithe air. time throughout the specification andclaim's.

Our invention is illustrated more or :less dia grammatically wherein-Figure 1 is a perspective, viewof a ing thevapplicationof the invention;g Figure 2 isa perspective view on a larger scale showing. the anchoragehousing; Figure 3 is a perspectiveviewon an enlarged scale showing theanchoragemeansi,

Figure 4 is a view on a transverse a larger scale through the device:

I is a strut adapted to support the wing of an airplane. strut along oneedge, to engage? bracket 3 along its other edge. 4 isan axleextendingoutwardly from the bracket 3, carryinga cable reel 5,'rot a'-tably mounted thereon and adapted to be yieldf ingly held in theretracted'or starting position by the spring 5. 1 is a cablewoundabout-the reel.

When the cable is in the position shown in Figure I, the spring 6 iscompressed, the spring 'B'being strong enough to draw the cable into thehousing and wind the cable about the reel. -23 is a hook section y 2 isa clamp adapted to engage the cable is fully extended, he allowsthe" pinH, to g at the end of the cable adapted to be hooked into the eyelet Inat the end of'the stake 9 if desired.

The stake illustratesgenerally any suitableanchorage means and theeyelet might be on a weight or embedded in the concrete floor of arunway or any other suitable means might be provided for holding theeyelet in position so that when the hook is engaged with the eyelet, theplane will be anchored.

II is a handle on the reel -5 whereby the reel maybe rotated if for anyreason the spring. 6 fails to operate. I2 is a housing made of two partsjoined by the hinge l3 and adapted to be latched by means of a springlatch l4. I5 is a curved extension on the bracket 3 adapted to enstillmanychanges mightbefma'deiinthe Size.

The purpose of this pin is of tomato lockthe" reel ga ns rotation either in the retracted orextendedpositionofthejanchor I agec blelll ZZis an aperture in -the -forward lower side"of theh'ousing I 2 through which the cable Tm'ay extend and is adaptedto be closed bya slide 23.

' .,When the hook 8 "is'releasedand thecable is wound about the reel 5by the s'pring 6, the hook 8 enters the housing through the'opening 22.The latch pi'n I1 is manipulated to lock the reel in position with thenoon 8immediately'adiacent theapertureor door 22 and the doo'r'is'closed by the slide '23; Under these circumstances; the plane maytravel, the 'airresistan'ce' being reduced to a minimum by the shape ofthe housing. 1 When itis desired to" anchor the plane,'- thel'slid'e "ispushed back,the operator'inse'rts his finger in'the' opening 22, takeshold'of the hook, pulls the cable out, having first released the "pin11. When the engage one 'of' the apertures 21' to anchor-the reeland'then hooks the eyelet onto the stake oronto i v any" other';-suitable eyelet on any other suitable anchorage; thusv anchoring theplane. This is done' on both-sidesofthe plane so that the two anchorcables hold the plane down tothe ground. It will be understood that thecables are short so that the angle the cable makes with the ground is Ea sharp one, thus avoiding I the danger of swinging or'kite like flyingofthe plane under adverseconditions.

It will be releasedthatwhile We have shownan operative device asillustrated in the drawings,

shape, number, arrangement'and disposition of parts without departingmaterially from the spirit of our invention. We wish,'therefore, thatour showing be takenas in a large, sense as -diaaxle rigidly mountedthereon, a reel rotatablyv mounted on the axle, a handle on the reel, ananchorage cord wound about the reel, yielding means for resistingrotation of the reel resultant from drawing out of the cable, amultiparthousv ing on the bracket enclosing the reel and handle,
